Description

  The present invention relates to a stamp using a porous stamping material capable of accurately marking a predetermined position of a member to be stamped.

  As for the above stamps, when not in use, the stamping surface is exposed so as not to contaminate other objects, the printing body of the stamp body mounted in the gripping cylinder is moved up and down between the stamp body and the gripping cylinder. In general, the cover is covered with a freely movable slide cover, or the printing portion of the stamp body is covered with an openable / closable lid. For example, in Patent Document 1, when the lock mechanism is released, the stamping operation is performed. An open / closed seal with a lid is described in which the inner cylinder is retracted and the lid is opened so that the marking surface comes into contact with the surface to be printed so that the marking can be performed.

  However, in the open / close type seal with the lid disclosed in Patent Document 1, even if the lid is opened by performing a stamping operation and the slide cover is retracted, the printed part of the stamp does not protrude from the tip of the slide cover. There is a problem in that it is difficult to accurately check the position of the marking surface, and it is difficult to accurately mark the predetermined position of the member to be printed.

Japanese Patent No. 3864010

  In the present invention, not only can a stamp similar to that of this type of stamp be made, but also a stamper can accurately check the position of the marking surface and can perform high-precision marking at a limited position. It is intended for stamps using sex stamps.

Stamp of the present invention to solve the problems described above, the grip tube and porous stamp body constantly lower end opening by the elastic force of the return spring between the lower portion of the stamp body provided therein In a stamp with a slide cover that can be moved up and down positioned below the marking surface of the printing unit , both the slide cover and the stamp body are provided with the return spring interposed between the outer casing formed on the stamp body and the slide cover. The above-mentioned stamp body can be moved up and down independently of the gripping cylinder by the elastic force of the return spring, and a part of the stamp body can be lowered by an external operation. The stamp body is moved up and down at the feeding position where the stamp surface of the stamp body is pressed down to a position below the lower end opening of the slide cover and the marking position can be visually observed. The Click locking mechanism is characterized in that is provided.

In order to make a part of the stamp body pushable by external operation, the top of the grip cylinder can be opened and the top of the stamp body can be knocked from the top of the grip cylinder. Other means such as providing a vertical groove in the barrel wall of the gripping cylinder so that the operation protrusion provided on the stamp body can intervene may be used, and the tip of the slide cover should be tapered. Is preferred.

  In the present invention, as described above, the lower end opening is always below the marking surface of the porous printing portion of the stamp body due to the elastic force of the return spring between the gripping cylinder and the lower portion of the stamp body mounted therein. Although it is a stamp with a slide cover that can be moved up and down so that the lower end opening coincides with the marking surface of the porous printing part by the stamping operation, the gripping cylinder is always covered so that the marking surface covers the periphery of the printing part of the stamping body In addition to being exposed to the outside due to the slide cover interposed between the two and the other, it does not contaminate other objects, and the normal stamp is applied to the part to be marked on the surface to be imprinted in the same manner as this type of conventional stamp. In this invention, the stamp body can be moved up and down in the gripping cylinder by the elastic force of the return spring, and a part of the stamp body can be pressed down from the outside. Exposed, and A lock mechanism is provided for locking the stamp body up and down at the extended position where the marking surface of the porous printing portion of the stamp body is pushed down to the position below the lower end opening of the slide cover. It is possible to carry out high-precision marking at a limited position while maintaining the state where the marking surface is exposed by the operation.

  In other words, if you want to print with high accuracy at a limited position on the member to be printed, first, hold the gripping cylinder and press down on the stamping body that is partly exposed to be pressed down from the outside. A locking mechanism provided to stop the stamp body from moving up and down at a position where the marking surface is pushed down from the lower end opening of the slide cover to a position below the lower end opening of the slide cover. Since it works and is locked, the stamping surface of the stamp body is exposed below the lower end of the gripping cylinder and slide cover. In this state, the position to be stamped must be accurately positioned and stamped. Since the stamp main body is held so as not to be moved up and down with respect to the gripping cylinder and the slide cover during this time, accurate printing is performed by the marking surface of the porous printing portion. After the stamping, if the lock mechanism is unlocked, the stamp body and the slide cover are lowered by the restoring force of the return spring, and the slide cover covers the periphery of the printing part of the stamp body. It will be restored to the normal state without polluting other things. In this way, the lower end of the slide cover is brought into contact with the marking surface and the normal marking with low positional accuracy is performed over the slide cover, and the positioning accuracy is determined by projecting the marking surface from the lower end of the sliding cover and visually locating the marking position. Since it can be switched to a high positioning seal by a simple operation, it is not necessary to prepare two types of stamps.

Furthermore, as in claim 1 , if the return spring can be used both as a slide cover that can be moved up and down and the stamp body, one type of return spring is sufficient, so that assembly is easy and cost reduction is achieved. Further, as described in claim 2 , in order that a part of the stamp body can be pushed down by an external operation, the upper end side portion of the gripping cylinder is formed as a notch opening for operating the knock portion. A part of the stamp body that can be pushed down by external operation through the notch opening can be a simple welfare that requires only a small number of parts, and the slide cover is applied to the part to be marked on the surface to be marked. When performing a normal stamping operation that pushes down the gripping cylinder, the problem that the cap-like halter is pushed down by mistake is reduced, and it is difficult to apply unnecessary force to the stamping surface, which is also effective for obtaining a clear stamped impression. in addition, as claimed in claim 3, In, that the tapered tip of the slide cover, the seal surface is so visually hardly be disturbed in the slide cover is facilitated, and can be more accurately positioned marking.

It is a side view which shows the state which extended the stamp main body of this invention. It is also a plan view. It is a perspective view similarly. It is a perspective view similarly. It is AA sectional drawing of FIG. It is BB sectional drawing of FIG. It is a partially cutaway perspective view showing a normal state of the stamp body. It is a partially cutaway perspective view showing the time of normal marking.

Next, a preferred embodiment of the present invention will be described in detail with reference to FIGS.
Reference numeral 1 denotes a stamp, which includes a gripping cylinder 2, a slide cover 3, a cartridge-type stamp body 4, and a return spring 5 for returning and sliding both the stamp body 4 and the slide cover 3. The sealing body 4 includes a lock mechanism 6 that stops the stamp body from moving up and down at a position where the marking surface of the porous printing portion of the stamp body 4 is pressed down to a position below the lower end opening of the slide cover 3.
As shown in FIGS. 5 and 6, the stamp main body 4 has a double structure holder in which the top of the head is connected to the inner top surface of the cap-like body formed on the knocking portion for pressing down. A cap-shaped receiving tube portion 4b having a slightly smaller diameter is connected to the lower portion of the member 4a, and the print cartridge 7 is mounted therein, and the front portion of the gripping tube 2 and the print cartridge 7 are mounted. A slide cover 3 is fitted between them so as to be movable up and down, and the stamp body 4 is also movable up and down inside the gripping cylinder 2.

  As shown in FIGS. 5 and 6, the gripping cylinder 2 is provided with a notch opening 22 for operating the knocking portion on the upper side of the lower cylindrical body 21 in which a step portion 21 a for locking the slide cover 3 is formed on the inner surface of the lower portion. The lower cylindrical body 21 and the upper cylindrical body 23 are formed on the upper inner surface of the lower cylindrical body 21 as shown in FIG. 21b and the engaging recess 23a formed in the upper cylindrical body 23 are engaged and integrated. Further, the above-described notch opening 22 is formed with a margin more than the slide stroke that knocks the top of the stamp body 4 and feeds it downward, so that the stamp body 4 is securely locked until the lock mechanism 6 is locked. Can be paid out.

  As shown in FIGS. 5 and 6, the slide cover 3 is formed on the upper cover cylinder 30 having an outer flange 30 a that engages with the step portion 21 a of the gripping cylinder 2 at the upper end, and on the lower inner surface of the upper cover cylinder 30. The lower cover tube 33 is formed with a locking piece 33a to be engaged with the stepped portion 30b. The lower cover tube 33 is tapered so that the position of a porous printing body 73, which will be described later, is visible from above. It is.

  The cap-shaped holder 4a described above is approximately half the length of the stamp body 4, and an outer collar 4c that abuts against the lower end edge of the upper cylindrical body 23 of the gripping cylinder 2 is formed at the lower end thereof. 4d is a step formed substantially in the middle of the receiving tube portion 4b as shown in FIG. 5, and the step 4d contacts the upper edge of the lower cover tube 33 of the slide cover 3 and the stamp body 4 is lowered. The lower end surface of the outer casing 4c is in contact with the upper end of the return spring 5.

  As shown in FIGS. 5 and 6, the return spring 5 is interposed between the outer cover 4c of the stamp body 4 and the outer cover 30a of the slide cover 3, and slides the slide cover 3 that has been slid backward during normal stamping into an old shape. At the same time, when the lock mechanism 6 with the stamp body 4 slid downward from the slide cover 3 and unlocked is released, the stamp body 4 is slid back to the old shape.

  As shown in FIG. 5, the lock mechanism 6 includes an elastic piece 60 that forms an outward protrusion 60 a of the stamp body 4 and a gripping cylinder 2 that engages and locks the protrusion 60 a of the elastic piece 60. The stamp body 2 is formed by knocking the stamp body 4 and feeding it downward, and the feeding is stopped when the step 4 d of the stamp body 4 comes into contact with the upper edge of the lower cover cylinder 33 of the slide cover 3. . At this time, the protrusion 60a of the elastic piece 60 is immersed and locked in the locking hole 2a, thereby preventing the stamp body 4 from returning to the old state by the urging force of the return spring 5. And the release of the lock is performed, for example, by lifting the clip 2b described later covering the locking hole 2a to expose the locking hole 2a and then pressing the protrusion 60a with the tip of the ballpoint pen from the locking hole 2a. Since the protrusion 60a comes out of the locking hole 2a, the stamp body 4 is restored to the old state by the urging force of the return spring 5. As another unlocking means, a spherical portion is provided at the tip of the clip 2b covering the locking hole 2a (not shown), and the protruding portion 60a is pushed by the spherical portion so that the protruding portion 60a is removed from the locking hole 2a. By detaching, the stamp body 4 can be returned to the old state by the urging force of the return spring 5, and in this case, the lock can be easily released using the elastic force of the clip 2b, which is convenient. .

  As shown in FIGS. 5 and 6, the print cartridge 7 has an ink replenishment cap 71 fitted on the upper end of a cylindrical body 70 formed with an outer collar 70 a for locking the stamp main body 4 at the front portion. The ink occlusion body 72 is fitted and locked to a diameter-enlarged recess 70 b formed on the inner surface of the front end portion of the cylindrical body 70, and the porous printing body 73 brought into contact with the ink occlusion body 72 is cylinderized by a metal fastener 74. It is attached to the lower end of the body 70. Note that the clip 2b is for carrying formed on the upper cylinder 23 of the gripping cylinder 2. The clip 2b in the illustrated example has the protruding portion 60a inadvertently blocked by the protruding portion of the tip thereof blocking the locking hole 2a. Although it is provided at a position where the extended state is not released by being pushed, the clip 2b does not necessarily exhibit the function described above, so the position of the clip 2b is a convenient position for carrying. There is no particular limitation as long as it is present.

  In the case of normal marking, when the gripping cylinder 2 is gripped in the state shown in FIG. 7 and the slide cover 3 is pressed against the marking surface, the slide cover 3 is attached with the return spring 5. Reversing against the force, the state shown in FIG. 8 is reached, and the marking surface at the lower end of the print cartridge 7 of the stamp body 4 comes into contact with the surface to be printed, and normal printing is performed. Since the periphery is covered with the slide cover 3, the marking position cannot be accurately positioned. For this reason, when it is necessary to accurately align the porous printed body 73 with the surface to be printed, if the knock portion of the stamp body 4 is pushed down with the finger through the notch opening 22, FIGS. 6, the stamp body 4 is drawn downward, and the marking surface of the porous printing body 73 protrudes downward from the lower end opening of the slide cover 3. By this feeding, the locking hole 2 a of the lock mechanism 6 is projected. The extended state is maintained by being fitted and locked to 60a.

  In this way, the position of the marking surface and the surface to be printed is confirmed by the synergistic effect of the projecting surface of the porous printed body 73 protruding from the slide cover 3 and the slide cover 3 having a tapered tip. Can be accurately positioned, so that it is possible to accurately perform marking at a limited position.

  In order to assemble such a stamp 1, first, the outer collar 30 a of the slide cover 3 fitted into the lower cylinder 21 of the gripping cylinder 2 is locked to the step portion 21 a of the lower cylinder 21. Subsequently, the outer collar 30a is brought into contact with and supported by the lower end of the return spring 6, the stamp body 4 is inserted into the gripping cylinder 2, and the outer collar 4c of the cap-shaped holder 4a is brought into contact with and supported by the upper end of the return spring 5. Subsequently, the lower cylindrical body 21 and the upper cylindrical body 23 are connected and integrated with the locking projection 21a and the locking recess 23a. Thereafter, when the print cartridge 7 is inserted from the lower end opening of the slide cover 3 and attached to the receiving tube portion 4b of the stamp body 4, the assembly is completed easily, so that the assembly can be easily performed.
